A cover device for a regulator, which has a purge button and a mouthpiece connected to the regulator, includes a body having a mouthpiece housing to receive the mouthpiece through an access opening which presents a friction fit to squeeze the mouthpiece passing therethrough in a squeezed state to enter and exit a hollow interior of the mouthpiece housing. The hollow interior is configured to store the mouthpiece in a relaxed state. A button cover is connected to the mouthpiece housing to cover the purge button on a top surface of the regulator when the mouthpiece is inserted into the hollow interior of the mouthpiece housing. The button cover is narrower in width than the mouthpiece housing.

A soft medical silicone edged cushion may significantly reduce air leakage and provide comfort to a wearer of a face mask, for example, when the face mask is continually worn by a healthcare worker for a twelve-hour shift of medical duty. The cushion may preferably be U-shaped and comprise a cross-section for holding an extra soft silicone gel or air, yet be sufficiently hard and elastic and of predetermined circumference to be adaptable to self-installation to the lateral edges of a face mask and coatable to protect from the escape of air and fit comfortably on a face despite the use of elastic straps with the face mask or the presence of solid plastic lateral edges of an oxygen mask or a ventilator mask. The cushion may be used to cushion a solid plastic laterally edged oxygen or ventilator mask against the use of elastic ties to tie the face mask around a patient's head. The face mask may comprise a UVC source of ultraviolet light controlled by buttons/displays/battery/USB charging port on the cushion or on a UVC cartridge replacing a filter of an N95 mask.

In an example, a cover device for a regulator, which has a purge button and a mouthpiece connected to the regulator, includes a body which has: a mouthpiece housing to receive the mouthpiece through an access opening which presents a friction fit to squeeze the mouthpiece passing therethrough in a squeezed state to enter and exit a hollow interior of the mouthpiece housing, the hollow interior configured to store the mouthpiece in a relaxed state; a regulator support connected to the mouthpiece housing to support a bottom surface of the regulator when the mouthpiece is inserted into the hollow interior of the mouthpiece housing; and a button cover connected to the mouthpiece housing to cover the purge button on a top surface of the regulator when the mouthpiece is inserted into the hollow interior of the mouthpiece housing, while exposing a portion of the top surface of the regulator surrounding the purge button.
